Feasibility of a geriatric comanagement (GERICO) pilot program for patients 75 and older undergoing radical cystectomy.	"BACKGROUND: Retrospective studies have shown the beneficial impact of geriatric comanagement (GERICO) on perioperative outcomes of older adults with cancer. We prospectively assessed the feasibility of perioperative GERICO for older adults with bladder cancer undergoing radical cystectomy. METHODS: We conducted a pilot study wherein all patients 75 years and older undergoing radical cystectomy between October 2019 and November 2020 were referred to the Geriatric Service preoperatively. Feasibility was defined according to the percentage of patients who received preoperative evaluation by the Geriatrics Service, who were followed for more than 80% of their inpatient days and who had their surgery rescheduled for logistical reasons. Urology advanced practice provider (APP) satisfaction with the program was measured via an 11-item survey. RESULTS: Sixty-six eligible patients underwent radical cystectomy in the stated time frame; 59 (89%; 95% confidence interval [CI], 79-97%) were referred to the Geriatric Service for evaluation. The median age of patients who had geriatric comanagement was 79 years; 40 (68%) were male. Forty-one patients (69%) were visited on at least 80% of the days in which they were not in the intensive care unit. No surgeries were rescheduled for logistical reasons. Nine of the 12 urology APPs (75%) responded to the survey; all nine ""somewhat"" or ""strongly"" agreed with statements indicating satisfaction with the program. CONCLUSION: Despite the challenges of the COVID-19 pandemic, we showed that perioperative GERICO is feasible. Fully powered prospective randomized controlled trials should be conducted to assess GERICO's impact on perioperative outcomes of older adults with cancer."	bladder
Conspicuity and muscle-invasiveness assessment for bladder cancer using VI-RADS: a multi-reader, contrast-free MRI study to determine optimal b-values for diffusion-weighted imaging.	OBJECTIVE: To (1) compare bladder cancer (BC) muscle invasiveness among three b-values using a contrast-free approach based on Vesical Imaging-Reporting and Data System (VI-RADS), to (2) determine if muscle-invasiveness assessment is affected by the reader experience, and to (3) compare BC conspicuity among three b-values, qualitatively and quantitatively. METHODS: Thirty-eight patients who underwent a bladder MRI on a 3.0-T scanner were enrolled. The gold standard was histopathology report following transurethral resection of BC. Three sets of images, including T2w and different b-values for DWI, set 1 (b = 1000 s/mm(2)), set 2 (b = 1500 s/mm(2)), and set 3 (b = 2000 s/mm(2)), were reviewed by three differently experienced readers. Descriptive statistics and Intraclass Correlation Coefficient (ICC) were calculated. Comparisons among readers and DWI sets were performed with the Wilcoxon test. Receiver operating characteristic (ROC) analysis was performed. Areas under the curves (AUCs) and pairwise comparison were calculated. RESULTS: AUCs of muscle-invasiveness assessment ranged from 0.896 to 0.984 (reader 1), 0.952-0.968 (reader 2), and 0.952-0.984 (reader 3) without significant differences among different sets and readers (p > 0.05). The mean conspicuity qualitative scores were higher in Set 1 (2.21-2.33), followed by Set 2 (2-2.16) and Set 3 (1.82-2.14). The quantitative conspicuity assessment showed that mean normalized intensity of tumor was significantly higher in Set 2 (4.217-4.737) than in Set 1 (3.923-4.492) and Set 3 (3.833-3.992) (p < 0.05). CONCLUSION: Muscle invasiveness can be assessed with high accuracy using a contrast-free protocol with T2W and DWI, regardless of reader's experience. b = 1500 s/mm(2) showed the best tumor delineation, while b = 1000 s/mm(2) allowed for better tumor-wall interface assessment.	bladder
Conditional survival of trimodal therapy for nonmetastatic muscle-invasive bladder cancer: A SEER database analysis.	OBJECTIVE: Conventional survival analysis plays a limited role in patients who have survived a period after initial treatment. The present study analyzed how conditional survival (CS) predicted survival rate over time for nonmetastatic muscle-invasive bladder cancer (MIBC) patients after trimodal treatment. METHOD: This retrospective study from the SEER database included consecutive patients with nonmetastatic MIBC who received trimodal therapy (TMT) between January 2010 and December 2017. Kaplan-Meier analysis was used to estimate overall survival (OS) and cancer-specific survival (CSS). CS was defined as the rate of surviving y years after already surviving for x years. Multivariate Cox regression analysis was used to identify prognostic factors. RESULT: A total of 1110 nonmetastatic MIBC patients treated with TMT were included. Given a 1-, 2-, 3-, and 4-year after TMT, the rate of surviving to 5-year, respectively, improved by +5.0 (20.0%), +17.0 (32.0%), +30.0 (45.0%), and +52.8 (67.8%) from those calculated at baseline (15.0%). The 2-year CS rate of patients who had survived 1-, 2-, or 3-year after TMT improved, respectively, compared to 3-, 4-, or 5-year actual survival. Multivariate Cox regression analysis demonstrated that adverse variables (T stage, age) of OS and CSS lost their prognostic significance over time. DISCUSSION AND CONCLUSION: Conditional survival rate of surviving to 5-year after TMT kept a relatively stable level over time. In addition, those adverse variables were not always the prognostic factors over time. Only age was always the significant prognostic factor for conditional OS from baseline to 5-year survival. Our results provided real-time survival information and prognosis estimates to adjust follow-up plans for nonmetastatic MIBC patients after TMT.	bladder
Molecular profile of pure squamous cell carcinoma of the bladder identifies major roles for OSMR and YAP signalling.	Pure squamous cell carcinoma (SCC) is the most common pure variant form of bladder cancer, found in 2-5% of cases. It often presents late and is unresponsive to cisplatin-based chemotherapy. The molecular features of these tumours have not been elucidated in detail. We carried out whole-exome sequencing (WES), copy number, and transcriptome analysis of bladder SCC. Muscle-invasive bladder cancer (MIBC) samples with no evidence of squamous differentiation (non-SD) were used for comparison. To assess commonality of features with urothelial carcinoma with SD, we examined data from SD samples in The Cancer Genome Atlas (TCGA) study of MIBC. TP53 was the most commonly mutated gene in SCC (64%) followed by FAT1 (45%). Copy number analysis revealed complex changes in SCC, many differing from those in samples with SD. Gain of 5p and 7p was the most common feature, and focal regions on 5p included OSMR and RICTOR. In addition to 9p deletions, we found some samples with focal gain of 9p24 containing CD274 (PD-L1). Loss of 4q35 containing FAT1 was found in many samples such that all but one sample analysed by WES had FAT1 mutation or deletion. Expression features included upregulation of oncostatin M receptor (OSMR), metalloproteinases, metallothioneins, keratinisation genes, extracellular matrix components, inflammatory response genes, stem cell markers, and immune response modulators. Exploration of differentially expressed transcription factors identified BNC1 and TFAP2A, a gene repressed by PPARG, as the most upregulated factors. Known urothelial differentiation factors were downregulated along with 72 Kruppel-associated (KRAB) domain-containing zinc finger family protein (KZFP) genes. Novel therapies are urgently needed for these tumours. In addition to upregulated expression of EGFR, which has been suggested as a therapeutic target in basal/squamous bladder cancer, we identified expression signatures that indicate upregulated OSMR and YAP/TAZ signalling. Preclinical evaluation of the effects of inhibition of these pathways alone or in combination is merited.	bladder
Serum microRNA as liquid biopsy biomarker for the prediction of oncological outcomes in patients with bladder cancer.	OBJECTIVES: Radical cystectomy is the gold-standard treatment for muscle-invasive bladder cancer and aggressive non-muscle-invasive bladder cancer. To enhance clinical decision-making regarding patients with bladder cancer who underwent radical cystectomy, a recurrence prediction biomarker with high accuracy is urgently needed. In this study, we developed a model for the prediction of bladder cancer recurrence after radical cystectomy by combining serum microRNA and a pathological factor. METHODS: We retrospectively analyzed the clinical records of 81 patients with bladder cancer who underwent radical cystectomy between 2008 and 2016. The dataset was divided into two, and Fisher linear discriminant analysis was used to construct a prognostic model for future recurrence in the training set (n = 41). The performance of the model was evaluated in the validation set (n = 40). RESULTS: Thirty patients had recurrence after having undergone radical cystectomy. A prognostic model for recurrence was constructed by combining a pathological factor (i.e. positive pathological lymph node status) and three microRNAs (miR-23a-3p, miR-3679-3p, and miR-3195). The model showed a sensitivity of 0.87, a specificity of 0.80, and an area under the receiver operating characteristic curve of 0.88 (0.77-0.98) in the validation set. Furthermore, Kaplan-Meier analysis revealed that patients with a low prediction index have significantly longer overall survival than patients with a high prediction index (P = 0.041). CONCLUSION: A combination of serum microRNA profiles and lymph node statuses is useful for the prediction of oncological outcomes after radical cystectomy in patients with bladder cancer.	bladder
Androgen receptor modulation and bladder cancer prevention - a short review.	The prevalence of bladder cancer (BCa) is 4 times higher in men as compared to women, and gender differences have been the focus of attention for few years. Androgen receptor (AR) may be a putative explanation for gender differences. It may also be related to unfavourable BCa progression and development because of the increased androgen sensitivity of urothelium to carcinogens. Moreover, cigarette smoking and occupational exposure to carcinogens have been reported to play contributory roles with the highest attributable risk of BCa. In this review, the authors attempt to summarize the seminal research works that synthesized current understanding of the central role of AR in the negative regulation of carcinogen detoxification activity in BCa. In particular, the authors discuss the regulatory effects of 3,3'-diindolylmethane on AR gene transcription through microRNA as its suggested effect on the prevention of BCa. Moreover, to show the still existing problem of occupational exposure and BCa incidence, the authors review recent studies in this area. Based on the rapidly accumulating scientific evidence, it seems pragmatic that androgen/AR-mediated interference in the detoxification mechanism may be inhibited by phytochemicals. Therefore, collectively, nutrition has a key role as gene-nutrient interactions are important contributors to BCa prevention, also through epigenetic modifications. Here, the authors have derived suggestions for future research. Med Pr. 2022;73(2):151-62.	bladder
Using Real-world Data to Define a Validated Nomogram for Advanced Bladder Cancer Patients Who Respond to Immunotherapy.	AIMS: Immune checkpoint inhibitors (ICIs) are used in incurable urothelial cancers, both in chemo-naïve and platinum-refractory patients. Efficacy and toxicity data published outside controlled clinical trials are limited. We report overall survival, progression-free survival and toxicities of ICIs in locally advanced (LABC) or metastatic bladder cancer (MBC). We aimed to develop and validate a prognostic model for these patients. MATERIALS AND METHODS: A multicentre real-world individual patient-level data study (n = 272) evaluating ICIs in the first-line platinum-ineligible or platinum-refractory setting for LABC/MBC between March 2017 and February 2020 was undertaken. Cox regression analyses evaluated the association of prognostic factors with overall survival. Data were split to create a training (n = 208) and validation (n = 64) cohort. The backward elimination method with a P-value cut-off of 0.05 was used to develop a reduced prognostic model using the training data set. The concordance index and assessment of observed versus predicted survival probabilities were used to evaluate the final model. RESULTS: The median follow-up was 18.9 (15.8-21.5) months. The median overall survival and progression-free survival in the training cohort were 9.2 (95% confidence interval 7.4-10.5) and 4.5 months (3.5-5.7), respectively. The most common grade 1/2 adverse events recorded were fatigue (47.8%) and infection (19.9%). Five key prognostic factors found in the training set were low haemoglobin, high neutrophil count, choice of immunotherapy favouring pembrolizumab, presence of liver metastasis and steroid use within 30 days of treatment. The concordance index for the training and validation cohorts was 0.66 (standard error = 0.05) and 0.64 (standard error = 0.04), respectively, for the final model. A nomogram was developed to calculate the expected survival probabilities based on risk factors. CONCLUSIONS: Real-world data were used to produce a validated prognostic model for overall survival in LABC/MBC treated with ICIs. This model could assist in patient stratification, interpreting and framing future trials incorporating PD-1/PD-L1 inhibitors in LABC/MBC.	bladder
REVIEW OF THE BLADDER CANCER MOLECULAR CLASSIFICATION PROPOSED: A NEW ERA - NEW TAXONOMY.	The management of bladder cancer patients largely depends on pathologic staging and grading, and current morphological classification does not always show the individual patient's risk. Despite modern surgical techniques, pre- and postoperative therapies, clinical outcomes of these patients have not changed over decades. Today, there are new biomarkers for bladder cancer showing changes in tumor biology and progression, as a result of changes in the pathways affecting cell signaling, proliferation, apoptosis, epigenetic changes, angiogenesis, and modulation of host immune response. Assessment of multiple biomarkers associated with those pathways offers new understanding of tumor behavior while identifying important panels of predicting patient management and outcomes. In this review, the most important molecules and basics of the novel molecular classification of bladder cancer are presented.	bladder
Reassessment of the Efficacy of Carboplatin for Metastatic Urothelial Carcinoma in the Era of Immunotherapy: A Systematic Review and Meta-analysis.	CONTEXT: Platinum-based combination chemotherapy is the standard treatment for advanced or metastatic urothelial carcinoma (AMUC). However, data comparing the efficacy of different platinum agents are limited. OBJECTIVE: This review aimed to assess the efficacy of carboplatin as a first-line treatment for AMUC using phase 3 randomized trial data. EVIDENCE ACQUISITION: Multiple databases were searched for articles published until August 2021. Studies that compared overall survival (OS), complete response (CR), and objective response rates (ORRs) in chemotherapy-eligible patients with AMUC were deemed eligible. EVIDENCE SYNTHESIS: Four studies were included. Compared with immune checkpoint inhibitor (ICI) monotherapy, neither cisplatin- nor carboplatin-based chemotherapy was associated with significant OS (hazard ratio [HR]: 0.97, 95% confidence interval [CI]: 0.85-1.11, p = 0.64 and HR: 0.90, 95% CI: 0.78-1.04, p = 0.16, respectively) and CR (odds ratio [OR]: 1.16, 95% CI: 0.70-1.92, p = 0.57 and OR: 0.89, 95% CI: 0.52-1.53, p = 0.67, respectively benefits, while both were associated with a favorable ORR (OR: 0.54, 95% CI: 0.40-0.74, p < 0.001 and OR: 0.58, 95% CI: 0.42-0.80, p < 0.001, respectively). A network meta-analysis (NMA)-based indirect comparison between carboplatin and cisplatin revealed that while cisplatin was slightly better than carboplatin in terms of OS, CR, and ORR, no significant difference was noted. CONCLUSIONS: Cisplatin- and carboplatin-based chemotherapies offer similar OS/CR benefits to ICI monotherapy and elicit a greater ORR than ICI monotherapy. Moreover, our NMA demonstrated that both cisplatin- and carboplatin-based chemotherapy have a similar efficacy in terms of OS, CR, and ORR. Given that carboplatin-based chemotherapy is shown to be more effective in contemporary series than in historical controls, it is strongly recommended that carboplatin be re-examined for its value in the era of ICIs and beyond. PATIENT SUMMARY: Cisplatin- as well as carboplatin-based chemotherapy is as effective as immune checkpoint inhibitors in terms of survival and eliciting a positive response. It is currently believed that cisplatin provides greater benefits than carboplatin; this requires re-evaluation.	bladder
Therapeutic targeting m6A-guided miR-146a-5p signaling contributes to the melittin-induced selective suppression of bladder cancer.	Abnormal RNA methylation and dysregulation of miRNA are frequently occurred in bladder cancer. Melittin is a potential drug candidate for intravesical chemotherapy against bladder cancer. However, the underlying epigenetic mechanism by which melittin-induced anti-tumor effect remains unclear. Here, we showed that melittin selectively induced apoptosis of bladder cancer cells in a METTL3-dependent manner. Ectopic expression of METTL3 significantly blocked melittin-induced apoptosis in vitro and in vivo. MicroRNA-sequence analysis identified miR-146a-5p suppression contributed to the melittin-induced selective antitumor effect. Further investigation revealed that METTL3-guided m6A modification methylated pri-miR-146 at the flanking sequence, which was responsible for the pri-miR-146 maturation. Moreover, NUMB/NOTCH2 axis was identified as a downstream target signal that mediated the pro-survival role of miR-146a-5p in bladder cancer cells. Importantly, METTL3 and miR-146a-5p were positively correlated with recurrence and poor prognosis of patients with bladder cancer. Our study indicates that METTL3 acts as a fate determinant that controls the sensitivity of bladder cancer cells to melittin treatment. Moreover, METTL3/miR-146a-5p/NUMB/NOTCH2 axis plays an oncogenic role in bladder cancer pathogenesis and could be a potential therapeutic target for recurrent bladder cancer treatment.	bladder
Optimal management of recurrent and metastatic upper tract urothelial carcinoma: Implications of intensity modulated radiation therapy.	BACKGROUND: Upper tract urothelial carcinoma (UTUC) is rare and the treatment for recurrent or metastatic UTUC is unclear. We evaluated the outcomes of salvage and palliative radiotherapy (RT) and prognostic factors in UTUC patients and find implications for salvage and palliative RT. METHODS: Between August 2006 and February 2021, 174 patients (median age, 68 years; range, 37-90) underwent salvage and palliative RT. Disease status at RT included initially diagnosed advanced disease (n = 8, 4.6%), local recurrence only (n = 56, 32.2%), distant metastasis only (n = 59, 33.9%), and local recurrence and distant metastasis (n = 51, 29.3%). The primary tumor location included the renal pelvis (n = 87, 50%), ureter (n = 77, 44.3%), and both (n = 10, 5.7%). Radical nephroureterectomy, chemotherapy, and immunotherapy were used in 135 (77.6%), 101 (58%), and 19 (10.9%) patients, respectively. Survival outcomes and prognostic factors were analysed using Cox and logistic regression analysis. RESULTS: Salvage RT and palliative RT was administered in 73 (42%) and 101 (58%) patients, respectively. The median radiation dose was 45 Gy (range, 15-65). Two-dimensional (2D) or three-dimensional (3D) RT and intensity modulated RT (IMRT) were used in 61 (35.1%) and 113 (64.9%) patients, respectively. The median follow-up was 7.8 months. The median duration of overall survival (OS) was 13.4 months, and the 1-year OS was 53.5%. The median progression-free survival (PFS) was 4.7 months, and the 6-month PFS was 41.9%. The 6-month infield PFS was 84%. In multivariate analysis, RT method (2D/3D vs. IMRT, p = 0.007) and RT response (p = 0.008) were independent prognostic factors for OS, and RT response correlated with PFS (p = 0.015). In subgroup analysis in patients with PD-L1 data, positive PD-L1 correlated with better PFS (p = 0.009). RT response-associated factors were concurrent chemotherapy (p = 0.03) and higher radiation dose (p = 0.034). Of 145 patients, 10 (6.9%) developed grade 3 acute or late toxicity. CONCLUSIONS: Salvage and palliative RT for UTUC are feasible and effective. Patients with RT response using IMRT may have survival benefit from salvage and palliative RT. Positive PD-L1 status might be related to radiosensitivity. High-dose radiation with concurrent chemotherapy may improve RT response.	bladder
[Immunotherapy in urologic oncology : Response and treatment interruptions due to adverse events in a bicentric real-world analysis].	BACKGROUND: Immune checkpoint inhibitors (ICI) have been approved in uro-oncology for a few years. Real-world experience regarding benefits and risks with novel side effects are rare. MATERIALS AND METHODS: In a retrospective analysis, all patients who received ICI therapy due to metastatic renal cell carcinoma (NCC) or urothelial carcinoma (UCA) were enrolled at two maximum care hospitals in Germany between July 2016 and May 2021. Radiologic response, progression-free survival (PFS), and adverse events leading to treatment interruption were collected. Oncologic response was compared to randomized controlled trials. RESULTS: In all, 1185 ICI cycles were administered to 145 patients (111 men [77%] and 34 women [23%]): 64 (44.1 %) patients with NCC and 81 (55.9%) patients with UCA received ICI therapy. Of 141 patients with radiological follow-up, an objective response was observed in 21.3% (n = 13) of patients with NCC and 20.0% (n = 16) with UCA (median duration of response 14.9 months [3.0-51.3]). Median PFS was 5.3 months in patients with NCC and 4.8 months with UCA. ICI-associated adverse events requiring treatment interruption were observed in 17.2% patients with NCC and 20.9% with UCA. These were most commonly renal (5.5%: nephritis) and gastrointestinal (4.8%: colitis, diarrhea) adverse events. Hospitalization was required for 22 (15.1%) patients. CONCLUSION: This real-world experience may support patient-centered consultation in treatment decision-making. Further studies on prognostic factors are needed. Therapy interruptions are frequent and the spectrum of side effects requires interdisciplinary treatment.	bladder
